CallerID [DTMF Version]
I have stopped working on this product but feel free to use it anyway! ;o)

About the software

  CallerID Server:
  • Takes care of all incoming calls.
  • If a unknown number is calling it will try to find the name of the caller on the internet.
  • Multiple client connections can be made.
  • Password protection. (to avoid unautorized clients to connect)
  • When a new number is calling it will save the new number in the database and if the caller name is found on the internet it will also be stored in the database.
  • Selectable port number.
  • Minimize to tray.

      CallerID Client:
  • Auto-connect to server at program start.
  • Auto-close popup can be set in seconds.
  • Debug windows
  • Full statistic. (Last calls, Top callers, Unregonized calls and Contact List)
  • Popup window with information about the current call.
  • Connect to the server from where ever you are. (depends on your firewall/router setup)

      CallerID Outlook Import:
  • Import all your contacts from Microsoft Outlook the the CallerID database.
  • Can update changed Outlook records with a current CallerID database.

      About all this software:
  • The software is developed by Jan Vinten and is freeware. If you like this software package then please go to the write me section and tell me about! ;o)

    About the hardware

  • 'General purpose' DTMF to RS232 converter. Transmits at 2400bps, 8E1 (even parity) in ASCII. Can be used with a standard terminal-program.
  • Ring-detection.
  • Can be built as either 'isolated' (between the phoneline and the serial-port), with external powersupply, or as 'unisolated', powered by the serial-port.
  • Based on standard-components. Can be built for less than $15.
  • Gives DTE possibility of autodetection of hardware/firmware-version (only possible on the unisolated version).
  • Can possibly be approved by the (danish) National Telecom Agency. As it is not approved, it's illegal to use on the PSTN in Denmark.

    How does the hardware work?
  • DTMF-numbers are transmitted at 2400bps, 8E1 (8 databits, even parity, 1 stopbit), as soon as it's detected. The firmware then waits for the tone to 'go away', and another one 'to arrive'. Only CLIP-sequences are transmitted if CLIONLY is set=1. Transmission is in ASCII, if ASCII is set to 1.
  • Ringing is checked, 'at the same time', and if detected, an 'R' is transmitted.
  • A typical CLIP-sequence (seen from the PC's serialport) could be "A12345678#RRRRR".
